All information on the current just-in-time solution from SAP
SAP has long had its own module with suitable functions for just-in-time and just-in-sequence delivery, known as SAP JIT. This module was updated with SAP S/4HANA and is now called SAP Next Generation JIT or NJIT. We examine what the module can do, who needs it and what changes there are compared to the previous solution.
What is Next Generation JIT from SAP?
SAP Next Generation JIT (abbreviated to NJIT or occasionally NG-JIT) is an extension within SAP S/4HANA. It is used to optimize production supply or delivery to customers according to just-in-time or just-in-sequence processes. This enables users to deliver goods or materials in the required quantities at the right time.
The predecessor solution SAP JIT is used by many companies today. With the switch to S/4HANA, however, the question arises as to whether the delivery processes should be switched to NJIT.
What functions does SAP NJIT have?
- Management of JIT control cycles: Create, customize and monitor JIT control cycles required for material replenishment in production supply areas (PSAs).
- Automated JIT and JIS call-offs: Automatic generation of call-offs based on defined control cycles, with integration into SAP S/4HANA Inventory Management and SAP Extended Warehouse Management (EWM).
- Integration with SAP EWM: Direct creation of tasks in SAP EWM to ensure seamless warehouse management and material movement.
- Support for external replenishment: Manage replenishment from external suppliers using SAP Transportation Management, combined with advanced shipping and receiving processes in SAP EWM to process inbound goods.
Advantages of SAP NJIT
The advantages of SAP NJIT lie primarily in the efficient implementation of JIT processes. This means that JIT processes have advantages and those who work with a suitable solution can fully exploit these advantages:
Reduced stock levels
By delivering materials exactly when they are needed, storage costs are reduced and space requirements are minimized.
Increased production efficiency
Ensuring that the right components arrive at the production line in the right order, reducing production delays.
Improved transparency
Real-time insights into the material flow enable proactive decision-making and a rapid response to changes.
Flexibility
Adaptation to specific business requirements, including the management of model year changes or technical modifications.
Integration
Full integration into the S/4HANA system with SAP TM and EWM is only possible with NJIT.
What's more, SAP users who map processes completely with SAP do not have to risk media disruptions, interface problems or transmission errors if they also map their JIT processes with an SAP module. Working with NJIT is then more transparent, efficient and automated than alternative third-party solutions.
What are the technical differences between SAP JIT and NJIT?
- User interface: SAP JIT is completely SAP GUI-based, while NJIT is based on Fiori. Accordingly, users work with the more modern interface.
- SOAP-based web services: With S/4HANA, SAP is increasingly relying on web services. For NJIT users, this may also mean switching to the Simple Object Access Protocol (SOAP) and thus moving away from the IDoc messages that were previously used.

For whom is Next Generation JIT interesting?
JIT and JIS processes are particularly widespread in the automotive industry. Manufacturers require very precise and punctual deliveries from their suppliers to ensure the efficient timing of automotive production. However, a supplier cannot manage this without digital mapping of these processes.
NJIT therefore also maps common process steps from this industry: Delivery orders or the processing of additional information such as RAN numbers are widespread in the automotive industry. These requirements can be implemented with the help of NJIT.
Get to grips with NJIT if you
- suppliers in the automotive industry,
- S/4HANA or want to use it in the future,
- customers in the USA,
- (have to) use delivery orders,
- must map RAN numbers, or
- Nissan or PSA in Europe.
